Abstract (en)
[origin: US2009151784A1] A multilayer anti-reflection structure for a backside contact solar cell. The anti-reflection structure may be formed on a front side of the backside contact solar cell. The anti-reflection structure may include a passivation level, a high optical absorption layer over the passivation level, and a low optical absorption layer over the high optical absorption layer. The passivation level may include silicon dioxide thermally-grown on a textured surface of the solar cell substrate, which may be an N-type silicon substrate. The high optical absorption layer may be configured to block at least 10% of UV radiation coming into the substrate. The high optical absorption layer may comprise high-k silicon nitride and the low optical absorption layer may comprise low-k silicon nitride.
